That’s just a fabulous production NumberTwo.
I worked with 1983 Wimbledon (losing) finalist Chris Lewis of NZ for quite a while (post his Wimbledon moment) on different ideas for improving his speed, power, agility etc because he had been hired to do the same for Ivan Lendl. Greats guys both of them btw.
Chris did the usual sprint warmup drills, prone starts, some max velocity stuff but mostly simple plyos (hopping double-foot, then single foot over small cones, some box jump combos but very low). But I really like how you took the twist of the service motion and applied it to your starts. Wish I had thought of that 20 years ago…
